SOLE-LEVELING MACHINE.

SPECIFICATION forming part of Letters Patent No. 540,222, dated May 28,1895.

Application filed March 8, 1893. Serial No. 465,176. (No model.)

T0 at whom it may concern:

Be it known that we, ERASTUS E. WINK- LEY and BENJAMIN PHILLIPS,citizens of the United States, and residents of Lynn, in the county ofEssex and Commonwealth of Massachusetts, have invented a new and usefulthe following is a specification.

Our invention relates to improvements in that class ofleveling machineryby which the operation of leveling is performed by a leveling rollapplied under pressure to the sole of the shoe, and consists of avibrating leveling roll and a shoe supporting jack, and intermediatemechanism operating automatically to change the relative longitudinalpositilon and lateral inclination of the roll and ac t.

Our invention further consists of the devices and combination of deviceshereinafter set forth and claimed.

The object of our invention is to produce a machine of the above classwhereby the operation of leveling a shoe may be performed without manualinterference of the operator after the shoe is in position to be actedupon by the roll, so that two or more machines placed in convenientjuxtaposition or assembled in what is known in the art as a gang machinemay be operated by the same operator, and a great saving of manual laborthereby effected.

Our invention is illustrated by the drawings herewith submitted, inwhich- Figure I is an end view of a machine embodying same. Fig. II is aplan view. Fig. III is a sectional view, enlarged, on line w m, Fig. 1.Figs. IV and V are respectively aface and reverse plan view of wheelforming part of said machine, showing face-cam and a portion ofperiphery-cam on same. Figs. VI, VII, and VIII are sectional viewsshowing another form of constructing a portion of said machine.

Similar letters and figures of reference refer to similar partsthroughout the several views.

Referring to the drawings, R represents the leveling roll shown asconcave, but the form of which may be varied. To the leveling roll R, weimpart a vibrating motion by the following mechanism: Mounted in frameA,-

which is a frame suitable to support the working parts of the machine,is a shaft B, to which power may be applied by any convenient device.The shaft B carries a roll 1, in which is cut the cam path 2. In the campath 2 runs the cam roll 3, carried by the pivoted lever 4, at or nearits lower end, the lever 4 beingintermediately pivoted to a suitablesupport on the frame A, and pivoted at or near its upper end to aconnecting rod 5, which is pivotally connected with the roll carrier bed6. The roll carrier bed 6 is free to slide in suitable ways in the frameA, and upon it is mounted the roll carrier 26, the outer end of which isforked and provided with hearings in which is mounted the leveling rollR.

We obtain and regulate pressure on the roll R as follows: The rollcarrier 26 at its inner end is pivoted to the roll carrier bed 6 andnormally rests on the same, its outer end carrying the roll R extendingbeyond the outer end of the carrier bed and curved downward to bring theroll R in convenient position to operate as hereinafter described. Uponthe carrier bed 6 near its outer end are mounted the springs 27-27 oneach side of roll carrier 26, which are secured to the cross-head 28extending across the same. Through the cross-head 28 runs the threadedbolt 29, which bears on the roll carrier 26 so that same is raisedagainst the tension of the springs 27-27, which tension may be regulatedby 7 raising or lowering the cross-head 28 by means of the bolt 29. Wefind it convenient to con struct the roll carrier in two parts capableof slight rocking motion with reference to each other, regulated byinterposed springs 30-30, so that the roll will be allowed slight playto adjust itself to the work.

- The last supporting jack is shown at E, but forms no essential featureof our invention. In the form shown in the drawings (Fig. I) it isprovided with standards forsupporting the last, adjustable vertically bymeans of set screws 31-31, and horizontal for different sizes of last byset screw 32.

To change the relative longitudinal position of the roll and jack wefind it preferable to oscillate the jack E, but we do not wish to limitour invention to such construction for it is evident that by a slightchange in the in- ICC termediate mechanism hereinafter described theroll B may be similarly oscillated and the same result secured. We wouldfurther say that by the term oscillating we wish to be understood asincluding a to and fro motion generally, whether along a rectilinear orcurvilinear path.

Apreferred form of mechanism for securing the above result is describedas follows: The shaft B carries a sleeve 7 on which is cut a worm 8. Thesleeve 7 is free to rotate about the shaft B, but is prevented bysuitable stops from sliding on the same. By a clutch mechanismhereinafter described the sleeve 7 may be made to rotate with the shaftB. In the frame A above and transversely to the shaft B is mounted ashaft 0, which carries keyed or otherwise rigidly secured thereto, aworm gear 9, which engages with the worm 8 on the shaft B. Upon theshaft 0 also rigidly secured thereto is a wheel D, having on its facethe path cam 10, the form and function of which will be hereinafter morefully set forth. In the path cam 10 runs the cam roll 12, carried by therod 13, the rear end of which is forked and embraces the shaft 0 and thefront end pivoted to the connecting rod 14, which is also pivotallyconnected with the arm 24, its connection therewith being renderedvertically adjustable by the circular slot 33.

The rod 13 is intermediately supported in bearing in standard 15. Thearm 24 supports the jack supporting carriage 22, in which is mounted inbearings 23-23, so as to be free to swing transversely, the lastsupporting jack E. The arm 24 is mounted upon suitable bearings in theframe A, upon which it is free to swing.

The relative lateral inclination of the roll and jack is changed eitherby rocking the jack E on longitudinal axis or rocking the roll R ontransverse axis. A form of mechanism for accomplishing this result bythe first of the above suggested methods is the following: Upon theWheel D is the periphery path cam 11, the particular form and functionof which will be hereinafter more fully described, in which runs the camroll 17, carried at or near the rear end of lever 18. The front end ofthe lever 18 is connected with the cross-head'19, which is mounted insuitable ways in which it is free to slide, the connection between thecross-head 19 and the lever 18 being arranged to allow play for swingingmotion of lever 18. The lever 18 is intermediately pivoted on frame A.To the cross-head 19 are secured the rigid downwardly extending arms2020, which embrace the handle ofthe crank lever 21, connected with andadapted to rock the last supporting jack E.

Our second method for accomplishing the above suggested result isdescribed as follows, particular reference being bad to Figs. VI, VII,and VIII of the drawings: The construction of roll carrier bed issimilar to that already described except that its sides, and ways in theframe A in which it slides, are

made circular to allow a rocking motion, and its connection withconnecting rod 5 is swiveled. The form and arrangement of roll carrierare similar to that already described, that is, it may be made in twoparts having a slight rocking motion with reference to each other, asindicated in Fig. VIII but such construction is not essential and theroll carrier may consist of a single casting or rigidly connected partsas shown in Fig. VI. The crosshead 19 is provided with a slot 35 intowhich extends a rigid arm 36 secured to the roll carrier bed. The slot35 is arranged to allow play for swinging motion of said arm 36.

It is evident from the foregoing description that in this constructionthe swinging jack supporting carriage 22 and the crank lever 21 areunnecessary as the jack has but one motion. These elements may thereforebe omitted and the jack rigidly mounted upon the arm 24.

The clutch mechanism on shaft B is described as follows: A sleeve 37 issplined to shaft B and free to slide thereon. The sleeve 37 is notchedto engage with notches on sleeve 7 and normally held in engagementtherewith by a spring 38, bearing against a collar on said shaft B. Inthe sleeve 37 is an annular groove in which runs a fork on the arm 39,which is free to rotate on rod 40, but prevented from sliding thereon bysuitable collars. The rod 40 is free to rotate and slide in suitablebearings in frame A, and is provided with an operating lever 41. Uponrod 40 is the rigid projection 42. On the wheel D is a dog 43 which uponrevolution of wheel D comes in contact with the rigid projection 42,

pushes out rod 40 and by arm 39, and its fork running in groove insleeve 37, disengages sleeves 37 and 7. By rotating rod 40, projection42 may be turned out of the way of the dog 43 and sleeve 37 thrown intoengagement with sleeve 7 by spring 38. The rod 40 may also be drawn outat any time by lever 41 and sleeves 37 and 7 disengaged.

As the wheel D revolves the cam roll 12 imparts a reciprocating motionto rod 13 which by connecting mechanism hereinbefore described impartsan oscillating or to and fro motion to the jack E. It is evident thatthe length of path over which such oscillation occurs, or the extent ofsuch motion, varies as the path cam 10 varies from circular form, andthat the position of jack with reference to leveling roll at any giventime may be determined by the position of the cam roll 12 on the pathcam 11. As the wheel D revolves, the cam roll 17 by lever 18 andconnecting mechanism hereinbefore described imparts a transverselyrocking motion to the jack E or rocks the roll R, the extent of rockingmotion varying as the path cam 11 varies from circular form, and theinclination of the roll at any given time to the sole of a shoe upon thejack E being determined by position of roll 17 in path cam 11. The pathcams 10 and 11, controlling these two movements, may be 540,223 I i s soconstructed as to produce any combinations.

i being slightly lower than the face of the sole they receive lesspressure from the roll. The downward action of the roll is limited bythe roll carrier bed 6 and by proper vertical adjustments of shoe uponthe last supporting jack, the pressure of the roll thereon being causedby the lifting of the roll thereby. The amount of the pressure andextent of action thereof may be limited, and the roll arranged to fallbut a short distance below the toe when it passes off the shoe.

By raising or lowering the rod 14 in the slot 33, the severaloscillations of jack E will be proportionately lengthened or shortenedbut the time in which a given oscillation occurs.

will be the same. The machine may thus be adapted for different sizes ofshoes, the sizes varying proportionately, and its operations will occurat the proper places thereon.

The operation of our machine is as follows: The machine beingin'adjustment to receive the size of shoe to be leveled, and power beingapplied thereto,the operator places a shoe on the jack E and adjusts thesame vertically as hereinbefore described. The lever 41 is then pushedout and the wheel D begins to revolve. The shoe is thereby carried underthe vibrating roll R, and moved to and fro, while the leveling roll Rvibrates over the same, under pressure of springs 27-27 varying itsinclination and length of operation on the different parts until thewheel D has made a complete revolution, when the clutch mechanism isthrown out and the operation ceases,
